had it fitted, but seems onlt happy in middle ring. Not Bothered about outer as gonna git a BG. But moving to granny causes chain grinding. Wondering if this is usual?
IMHO the Crud chain device (AKA D.C.D.) is not worth having.As you say the chain rubs a lot.The only way I found to correct this is to try "tweeking" the device with a large spanner to try and slightly bend it to line up better with the chain line.
Maybe this would suit you better since you are getting rid of the outer ring ??:DMR Bikes
I battle for hours trying to get the bloody thing working with out rubbing! The LBS told me that I should use a bit of inner tube and wrap it around the pulley to provide a wide bed for the chain to roll on!
